I want to recommend that you use weight gloves when you lift weights or use machines at a gym.They help to ensure that you are safely gripping the barbells or weight bars (you can break a toe if you drop a barbell out of your hands, or loose your grip while lying on your back, doing a chest press with a bar), as well as protecting the skin on the palm of your hands from pain and calluses.

In some hard-core muscle gyms, you'll find mostly men, using weight belts. I don't use one and most trainers don't recommend them for recreational lifters. If you use good form, and keep one corner of your mind on engaging your core at all times when you lift, you shouldn't need a weight belt.
